Tri City Launcher springs
So back before Caltracs these were the ticket for Stockers. Greg a Stocker Mopar racer copied Mopar SS springs for GM products. Front of the spring pack stacked and clamped. I got a best 60 ft of 1.51 with a 9" slick in my 78 TA with them. Since I have the Camaro now tacking the TA back to street cornering.
Passenger side spring closer in the picture.

Similar to what I did on my own, I cut the ends / eyelets off a second set of springs used that one for spring #2 and just removed the smallest one in effect it makes the front segment more resistant to wrap up and more like a trailing arm, clamping helps to stiffen and separation on deceleration

Very cool, thanks for posting! Did you have any option as far as ride height was concerened?
I remember talking to Greg many years ago in regards to ordering a set. I think he had a location in California and Michigan at the time. |

Paul it rode like a freaking dump truck! Part of why they are coming off and they lifted the car almost 4". Thye have 5 leafs in them vs the Firebird 4 leafs also.
They flat worked though. On the 78 when racing NMCA I tried just the Herb Adams relocating front spring eye up 3/4" for increased antisquat, then that plus a slapper bar before I ordered these from Greg. I did have the replacement springs made with the second leaf all the way to the spring eye.

Instead of buying from Greg I ended up dealing with Landrum. I was quite happy with them and still have the originals in my 74 that has been mid 1.3 60 ft with Cal-tracs weighing 3860. My brother with the Firebird ran the Landrums for years but recently switched to the Calvert split monos and likes them a lot. My other brother with the Z/28 had some Landrums made with the second leaf extending over the spring eye. They worked great but he hated the harsh ride. |

Squatted with stock springs not with these. I would have them de arched if I ever wanted to use them again. Looked like I had air shocks on it!
